Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a cylinder which is open on both sides, horizontally and rotatably supported, and has no holes, and which is connected to the individual chambers via a conveying screw fixed in the cylinder. A central pipe is provided along the central axis of the cylinder to which washing water, washing liquid, steam, etc. The present invention relates to a washing machine in which the washing process is carried out by forward and reverse partial rotations of the cylinder, whereas the transport of the laundry to the next chamber is carried out by a unidirectional 3600 rotational movement of the cylinder.

In such a known washing machine (Japanese Patent Publication No. 52-25665), the individual screw faces of the transport screw have holes through which the washing liquid can flow from chamber to chamber.

In this known washing machine, it is not possible to isolate the washing liquid in the individual chambers.

Therefore, in one washing machine, each processing area consists of at least one chamber, for example a pre-wash area, a main wash area,
It is possible to carry out independent treatments in the rinsing area. Furthermore, it is impossible to wash different types of laundry, for example colored fabrics and white fabrics, at the same time. The object of the present invention is to completely separate the washing liquid and the rinsing liquid in different chambers so that different types of laundry can be washed in the individual chambers. In order to solve this problem, according to the present invention, there is no hole in the entire screw surface, and at least one discharge opening is provided in the cylindrical surface of each chamber, and the cylindrical tube is opened until the washing liquid flows out before the conveying rotation. is stopped at the washing liquid discharge position.

The washing liquid in each chamber is completely isolated by having no holes in the screw surface of the conveying screw and allowing the washing liquid to flow out from all chambers before the rotational movement of the conveying cylinder. .

Since each chamber operates independently of each other, each chamber can perform different washing processes or wash different laundry items. An embodiment of a washing machine according to the invention is shown in detail in the drawing below.

The invention will be explained below with reference to the embodiments shown in the drawings.

A washing cylinder is shown at 1, which is open on both sides, horizontally supported and unperforated, and which is connected via suitable means not shown in the drawings for the sake of clarity. It can be rotated in one direction or even in both directions.

The washing cylinder 1 is separated into individual chambers 3 via a conveying screw 2, the division being effected by the screw face of the conveying screw 2.

A central pipe 4 is provided on the central axis of the washing cylinder 1 to which washing water, washing liquid, steam, etc. are supplied. As can be seen particularly clearly in FIG. 1, this central tube 4 is divided by a screw surface into individual central tube sections 4a. The screw face is not perforated and therefore there is no connection between the individual chambers 3.

Each central tube section 4a is provided with an outlet opening 5 through which detergent is introduced into the individual chamber 3. It is of course within the scope of the invention to provide only a single outlet opening instead of multiple outlet openings 5 in each central tube section 4a. Each cylindrical surface 1a associated with the corresponding chamber 3 is provided with at least one discharge opening 6 through which the used liquid etc. can be discharged.

Needless to say, this used liquid is not simply discharged outside, but rather is led out to a drain or the like that sends this used liquid to a regeneration device. For clarity, this drain or conduit is omitted from the drawings. The operation of the washing machine according to the invention is as follows.

The laundry mass is introduced into the first chamber 3 of the cylinder 1 via the inlet hopper 7.

The entire chamber 3 is then filled with detergent via the central tube 4 and the outlet opening 5. The washing cylinder 1, and in particular the discharge opening 6, then occupy the zero position shown in FIG. Now the actual washing process begins, which is carried out by approximately 2400 partial rotations of the washing cylinder 1 in forward and reverse directions.

The cylinder 1 alternately occupies the positions according to FIGS. 2 and 3 during this forward and reverse partial rotation. This partial rotation of the cylinder is the sixth
It is shown in the figure by a sawtooth curve, while the end point of the partial rotation indicates the 0 or 240 part position of the washing cylinder. The last partial revolution of this first washing process ends with approximately 600 additional unidirectional revolutions of the cylinder 1 into the position shown in FIGS. 1 and 4.

The cylinder 1 then stops for a short time. The discharge opening 6 is then located at the lowest position of the cylinder 1, so that the used liquid can be discharged. At this position, the cylinder 1 is rotated by 240 + 60 = 300 yen in one rotational direction (see position 3000 in Fig. 6). After draining the liquid, the cylinder 1 is rotated a further 600 degrees to the position shown in FIG.
This means that a complete rotation of 00 has been completed.

This rotational movement of the cylinder 1 by itself 3603 causes the laundry to be conveyed from the chamber 3 which is completely to the left in FIG. 1 to the immediately next chamber 3. Chamber 3 is now filled with detergent for the second washing process, and chamber 3 on the left in FIG.
can be fed with the next batch of laundry, both of which can take place both during a short stoppage of the washing cylinder 1 and during the start of a forward and reverse partial rotation (as shown by the curves in FIG. 6). 360 position).

The laundry discharge and transport process is now repeated in the same way.

In this way, the laundry mass moves from chamber 3 to chamber 3 and is discharged one by one at the outlet side 8 of the cylinder 1. This takes place during the phase of rotation of the cylinder 1, indicated by hunting in FIG. It is clear that the washing machine according to the invention can be combined with a charging device and a removal device for periodically feeding or discharging laundry blocks.
